version 1.2.6: metadata enhancements, SNR improvement, improved clipping protection behaviour

Metadata enhancements

Native metadata now works for the following file types: wav, aiff, caf, flac, oga, rf64

This means that when converting between these file types, metadata will be transferred from the input file to the output file.

Please note that aiff files only support the "name" and "artist" fields.

To disable the transfer of metadata from input file to output file, use the --noMetadata option

ID3 tags are not supported yet. The above refers only to the native (built-in) metadata supported by each of the above formats. Also, Since dsf files use ID3 chunks, this means that metadata from dsf files is not read

Slight improvement in SNR (Signal-to-noise ratio) for complex conversion ratios

Changed Kaiser Window sidelobe attenuation from 140dB to 160dB for complex ratios.

Improved clipping protection behaviour

when reducing the gain, clipping detection will nudge the gain down by an addional fraction of an LSB to avoid unnecessary clipping detection loops.
